Picea: Our Integrated Home Energy System for Self-Sufficiency

We offer the Picea series, such as Picea 2, an all-in-one energy system integrating electrolyzer, hydrogen storage, and fuel cell. It uses photovoltaic power to produce and store hydrogen, and in winter, the fuel cell generates electricity and heat, enabling households to achieve energy self-sufficiency.

Why choose us?

Diverse electrolyzer technology coverage

We offer alkaline, PEM, and AEM electrolyzers, catering to needs from large-scale industry (alkaline) to renewable integration (PEM) and cost-efficient innovation (AEM).

Mature and stable alkaline electrolyzers

Our alkaline electrolyzers with KOH electrolyte feature mature technology, high operational stability, and low water purity requirements, ideal for large-scale industrial hydrogen production.

AEM electrolyzers balance cost and efficiency

AEM electrolyzers merge alkaline's cost advantages with PEM's efficiency, using non-precious metal catalysts, suitable for emerging commercial scenarios.

The electrolyzer storage in Picea refers to the integrated electrolyzer and hydrogen storage unit. The alkaline electrolyzer (70–80% efficiency) produces hydrogen from water using surplus solar power, which is then stored in dedicated tanks. This combined system eliminates the need for external hydrogen infrastructure, making it suitable for remote or grid-constrained locations. The electrolyzer operates in conjunction with a battery to handle short-term energy fluctuations, while hydrogen storage handles long-term needs. The Picea 2’s compact design (70% lighter than previous models) further optimizes space for integrated electrolyzer-storage units.

Frequently Asked Questions

What is the efficiency of your PEM electrolyzers?

Our PEM electrolyzers boast an efficiency of over 80%, making them highly efficient for hydrogen production. This high efficiency, combined with fast response times, makes them ideal for integration with renewable energy sources like wind and solar.
Yes, our alkaline electrolyzers have low requirements for feedwater purity. This makes them well-suited for areas with lower water quality, reducing the need for extensive water treatment and lowering overall operational costs.
Our fuel cells, especially PEMFCs, are designed for durability. With proper maintenance, they can have a long operational lifespan, suitable for continuous use in various applications such as transportation and distributed power generation.
Our metal hydride storage systems offer high hydrogen density through chemical reactions with metals such as magnesium, titanium, and zirconium. The maximum capacity varies by model, with options tailored for small-scale applications. For home use, typical models can store enough hydrogen to meet daily electricity and heating needs, while on-vehicle versions support extended vehicle range. All are optimized for compactness and safety, fitting seamlessly into their respective scenarios.
